1.1 本指南涵盖了完整沉积物数据集的标准。 1.2 本指南提供了收集非粘性沉积物冲积数据的指南。 1.3 本指南描述了应测量和存储哪些参数，以获得完整的泥沙和水力数据集，该数据集可用于使用任何著名的泥沙输运方程计算泥沙输运。 1.4 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 本指南描述了应测量和存储哪些参数，以获得完整的泥沙和水力数据集，该数据集可用于使用任何著名的泥沙输运方程计算泥沙输运。 5.2 该标准仅涉及非粘性沉积物的数据收集。非粘性沉积物是由离散颗粒组成的沉积物，其运动取决于颗粒本身的特殊性质 ( 1. ) . 这些特性可以包括颗粒大小、形状、密度和相对于其他颗粒在河床上的位置。通常，砂、砾石、鹅卵石和巨砾被视为非粘性沉积物。

1.1 This guide covers criteria for a complete sediment data set. 1.2 This guide provides guidelines for the collection of non-cohesive sediment alluvial data. 1.3 This guide describes what parameters should be measured and stored to obtain a complete sediment and hydraulic data set that could be used to compute sediment transport using any prominently known sediment-transport equations. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 This guide describes what parameters should be measured and stored to obtain a complete sediment and hydraulic data set that could be used to compute sediment transport using any prominently known sediment-transport equations. 5.2 The criteria will address only the collection of data on noncohesive sediment. A noncohesive sediment is one that consists of discrete particles and whose movement depends on the particular properties of the particles themselves ( 1 ) . These properties can include particle size, shape, density, and position on the streambed with respect to other particles. Generally, sand, gravel, cobbles, and boulders are considered to be noncohesive sediments.
